## In TeXForm

TeXForm parses this entry as prefix syntax; the package determines its argument specification.

## Equivalent forms

```latex
\quantity
```

exact. MathJax maps both names to the same parse method with the same parameters, including the optional paired-delimiter form and the no-argument fallback.
